Patent GB-774506-A (GB)
Title: Improvements in and relating to the automatic control of dough-dividing and kneadingmachines
IPC: A21C5/08
Filed: 1953-03-10
Abstract: 774,506. Dough-dividing and -kneading machines. SCHRODER, H. March 10, 1953 [Dec. 9, 1952], No. 16785/55. Divided out of 774,504. Class 87(2). [Also in Group XXIV] Relates to a dough-dividing and - kneading machine of the type having a gyratory kneading plate 1, Fig. 1, an insertible dough-supporting plate 219 superposed on plate 1, a dough-pressing head 7 having a knife spider therein, a doughsurrounding ring 3 and a hand-lever by which the machine is started, the machine then automatically carrying out all the dough-working operations and finally stopping itself. According to the invention means are provided for preventing the starting of the machine if the dough-supporting plate 219 is inserted into the machine in the wrong position. In the electrically-controlled machine shown in Figs. 1, 3 and 5 the correct position of plate 219 is determined by a pin 220 secured to plate 1, this pin entering a locating hole in plate 219. If, for example, a lump of dough has been left on plate 1, plate 219 will not seat properly on plate 1 but will be tilted up. The machine is started by rocking a hand lever 227 about a pivot 226 from the Fig. 1 position to the Fig. 3 position, whereby one link 228 of a toggle linkage 228/229 closes a starting switch 235. If plate 219 is improperly positioned, this switch closing movement is prevented by abutment of a feeler 232 against the plate, this feeler being secured to link 229. The feeler acts as a guard precluding hand access to the dough-working machinery. Springs 234 tend to raise the feeler. There may be two feelers. Sequential operation:- (1) A switch 242, Fig. 5, is closed to start an electric motor 123, whereby one element 126, Fig. 1, of a clutch 126/169 is set in motion. (2) The hand-lever is moved to close switch 235, thereby energizing an electromagnet 214 which, via arm 210, engages 169 with 126, whereupon a worm 135 turns worm wheel 26 and hence shaft 33 clockwise through one complete revolution to perform one cycle of kneading movements, as described in Specifications 774,504 and 774,505. (3) During the kneading operation the head 7 rises and, via a catch 240 thereon, rocks the toggle linkage to allow switch 235 to open : but magnet 214 is still energized through a switch 218, which closed when wheel 26 started to turn. (4) When a cam 216 on wheel 26 reaches switch 218 that switch is opened, the magnet is deenergized, the clutch opens and the machine stops. Figs. 6 and 7 show a machine having a mechanically-operated safety device. The handlever 227 and toggle 228/229 are as described above, but the downward movement of the handlever is transmitted by linkages 250, 253, 254, 258 to pin 180 to raise a lever 173 to allow a control shaft to perform one revolution as described in Specification 774,504. In modifications (not illustrated) (a) a feeler or apron may be pivotally connected to the lever mechanism 227, 228 and acted upon by spring 234, and (b) two feelers may be used.

Filed: 1954-06-09
Abstract: 755,781. Pneumatic separating; sifting apparatus. TOPP, H. J. B. June 9, 1954, No. 16976/54. Class 117. Loose material is graded by forming it into a moving annular curtain, through which is directed an airstream substantially at rightangles. In one embodiment, the material is fed down a tube 104, Fig. 6, to a spreader 164 rotating with a conical screen 156. The material which fails to pass through the screen falls into an annular trough 162 whence it is swept by blades 159, rotating with the screen, to an outlet 163. The screen is cleaned by a fixed brush 166. Material passing through the screen falls on to the surface of a rotating air chest 108 which forms the base of a " basket " the side wall 106 of which may be composed of a series of hoops or a single perforated conical sheet. The material is guided by fixed blades 114 to an annular orifice 113 between the members 106, 108 whence it falls through the annular duct 119 between the chest 108 and a depending skirt 118 of rubber &c. Air emerging radially from an adjustable peripheral orifice 115 at the bottom of the airchest 108 acts on the falling curtain of material which is separated into a heavier fraction which falls into trough 125 and a lighter fraction which falls into trough 126. Radial vanes 122, rotating with the air chest, sweep the contents of the troughs to outlets 129, 131, respectively. Air is drawn into the airchest 108 through apertures 133 by a fan 144 driven by shaft 146 while the airchest and sieve are driven by a coaxial hollow shaft 134. In some embodiments, Figs. 1, 3 and 4 (not shown), the screen is omitted. In another embodiment, the annular stream of material moves horizontally, air being passed downwardly therethrough. The material is fed from a hopper 222, Fig. 12, on to the conical spreader 229 of a rotating spinner disc 224, provided with vanes 231, which propels the material horizontally to form the annular stream. A blower 251 feeds an annular airchest 249 surrounding the hopper 222 and provided with an annular downwardlydirected nozzle 252 which produces an airstream perpendicular to the flow of the material. The dimensions and position of the nozzle may be made adjustable and it may be replaced by a plurality of closely-spaced jets. The annular collecting troughs 234, 235, 236 are formed by rotating partitions 232, 233 and scrapers 237a, 237b and 237c convey the separated materials to the outlets 244, 246, 248 respectively. A fixed scraper 254 co-operates with the partition 233.

[Class 87 (ii)] Relates to the apparatus described in the parent Specification for producing facing patterns on bricks, tiles, and the like and consists in housing the two indent plates for producing the pattern on the "header" ends of bricks in the common wall of the "duplex" mould box described. The two indent plates are operated by a single wedge-shaped member. The indent plates f housed in the suitably recessed common wall e of the two moulds a are cut away on the inner sides at an inclination and engage the correspondingly inclined sides of the wedge member d. Swallow-tailed ribs g formed on each side of the member d engage corresponding recesses in the plates f so that a downward movement of the member d will withdraw the indent plates into the wall e and an upward movement will cause them to move apart into their respective mould boxes, as shown in the Fig., to impress their pattern on the bricks in the mould. To keep the brick material in sufficiently plastic condition, the indent plates fare preferably heated. This may be done by an electric heater h housed in a transverse slot in the wedge member d. The walls of the moulding box through which the heater leads are brought are suitably slotted to allow the leads to move up and down with the member d.
